[0001] The present application relates to the technical field of sealed containers, and in particular to a sealed storage tank. Background Art

[0002] A storage tank is a container for storing goods and materials, usually including an upper cover and a tank body with a storage cavity having an opening at one end, and the upper cover and the open end of the tank body are detachably connected. Remove the upper cover, put the goods into the storage cavity, and then put the upper cover back on the open end of the tank body and reconnect it to transport and store the goods.

[0003] Among them, some special goods, such as flammable and explosive goods, goods with odors that need to be prevented from volatilization, or goods in the form of gas, have higher requirements on the sealing performance of storage tanks. However, the existing storage tanks only simply plug the upper cover into the open end of the tank body, and there is a gap between the upper cover and the side wall of the tank body, which is not sealing enough.

[0004] Therefore, how to improve the sealing performance of the storage tank has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In order to improve the sealing performance of a storage tank, the present application provides a sealed storage tank.

[0006] A sealed storage tank is provided to achieve the purpose of the utility model, comprising:

[0007] Tanks, covers and seals;

[0008] The tank body is provided with a preset cavity with an opening at one end, the opening is located at one axial end of the tank body, the sealing cover matches the opening of the tank body, and the sealing cover is suitable for covering the open end of the tank body to seal the preset cavity;

[0009] The outer edge of the sealing cover protrudes out of the radial side wall of the tank body, and the sealing part includes a threaded rod, a sealing nut and an arc-shaped handle. One end of the threaded rod is detachably connected to the outer wall of the tank body, and the other end of the threaded rod passes through the end of the sealing cover that protrudes out of the side wall of the tank body and is threadedly connected to the sealing nut. The arc-shaped ends of the arc-shaped handle are connected to the outer wall of the sealing nut.

[0010] Compared with existing storage tanks, in which the cover and the tank body are simply plugged in without external pressure, resulting in insufficient sealing of the tank, the present application can continuously pressurize and seal the cover and the tank body through a threaded rod and a rotating sealing nut, thereby reducing the gap between the cover and the side wall of the open end of the tank body, improving the sealing performance of the storage tank, ensuring the storage safety of goods and materials, and facilitating the long-term storage of goods.

[0019] In addition, in order to better illustrate the present application, numerous specific details are provided in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods and means well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0020] The present application provides a sealed storage tank, comprising a tank body 100, a sealing cover 200 and a sealing portion. The tank body 100 is provided with a preset cavity with one end open, the opening being located at one axial end of the tank body 100, the sealing cover 200 matches the opening of the tank body 100, and the sealing cover 200 is suitable for covering the open end of the tank body 100 to seal the preset cavity; the outer edge of the sealing cover 200 protrudes out of the radial side wall of the tank body 100, the sealing portion comprises a threaded rod 310, a sealing nut 320 and an arc-shaped handle 321, the long end of the threaded rod 310 is connected to the tank body 100, and the sealing nut 320 is connected to the arc-shaped handle 321. 0 outer wall is detachably connected, the other end of the threaded rod 310 passes through the cover 200 and protrudes out of one end of the side wall of the tank body 100 and is threadedly connected to the sealing nut 320, the arc-shaped ends of the arc-shaped handle 321 are connected to the outer wall of the sealing nut 320, a preset distance is set between the arc-shaped middle part of the arc-shaped handle 321 and the sealing nut 320, and a preset distance is set between the arc-shaped handle 321 and the threaded rod 310 to make way, so as to ensure the relative displacement between the threaded rod 310 and the sealing nut 320.

[0021] The present application provides a tank body 100, which is provided with a preset cavity with one end open to store goods and materials; provides a cover 200, which covers the open end of the tank body 100 to seal the preset cavity; and provides a sealing portion, wherein one end of the threaded rod 310 is connected to the outer wall of the tank body 100, and the other end penetrates the cover 200 and is threadedly connected to the sealing nut 320. The sealing nut 320 is rotated to drive the displacement of the sealing nut 320 on the threaded rod 310, shortening the distance between the sealing nut 320 and the end of the threaded rod 310 connected to the outer wall of the tank body 100. During the displacement of the sealing nut 320, the cover 200 is continuously pressed downward, and the cover 200 follows the downward movement of the sealing nut 320 to continuously press against the open end of the tank body 100, thereby reducing the gap between the cover 200 and the open end of the tank body 100 and improving the connection sealing performance between the cover 200 and the open end of the tank body 100. Compared with the existing storage tanks, in which the cover and the tank body are simply plugged in without external pressure, resulting in insufficient sealing of the tank, the present application can continuously pressurize and seal the cover 200 and the tank body 100 through the threaded rod 310 and the rotating sealing nut 320, thereby reducing the gap between the cover 200 and the side wall of the open end of the tank body 100, improving the sealing performance of the storage tank, ensuring the storage safety of goods and materials, and facilitating the long-term storage of goods.

[0022] It should be noted that the present application does not impose any specific restrictions on the connection structure between the cover 200 and the open end of the can body 100, as long as the two are matched and fit, and can be continuously fitted and brought closer under the action of the threaded rod 310 and the sealing nut 320 to reduce the gap. A cylindrical protrusion matching the opening of the can body 100 can be provided in the middle of one side of the cover 200, and the cover 200 is plugged into the open end of the can body 100 through its protrusion.

[0023] In addition, the sealing nut 320 of the present application is provided with an arc-shaped handle 321, and the arc-shaped ends of the arc-shaped handle 321 are connected to the annular outer wall of the sealing nut 320. The operator holds the arc-shaped hole of the arc-shaped handle 321 to rotate the sealing nut 320, which is convenient for holding and operating. In addition, the arc-shaped handle 321 is also the lifting lug of the sealed storage tank. The arc-shaped handle 321 and the outer wall of the sealing nut 320 form a closed arc hole. Therefore, after the sealing part is used to seal the cover 200 to the open end of the tank body 100, the end of the cover 200 away from the tank body 100 is provided with a lifting hole (the aforementioned arc hole). After filling materials into the sealed storage tank and sealing, the sealed storage tank can be moved by lifting equipment for easy transportation and warehouse storage.

[0024] In a possible implementation, the outer wall of the tank body 100 is provided with a connection portion, and one end of the body length of the threaded rod 310 is detachably connected to the connection portion. Furthermore, the sealing portion also includes a connection rod 330; a connection hole is provided at one end of the body length of the threaded rod 310, and the connection hole penetrates the two end side walls of the threaded rod 310 along the body width direction, and the connection rod 330 passes through the threaded rod 310 through the connection hole, and a movable gap is provided between the connection rod 330 and the threaded hole to facilitate the insertion, connection, withdrawal and disassembly of the connection rod 330 and the threaded rod 310. One end of the connection rod 330 that passes through the threaded rod 310 is detachably connected to the connection portion.

[0025] Furthermore, the connecting portion includes a first connecting member 111 and a second connecting member 112 that are arranged opposite to each other, and one end of the body length of the threaded rod 310 with a connecting hole is located between the first connecting member 111 and the second connecting member 112, and one end of the body length of the connecting rod 330 passes through the first connecting member 111, the threaded rod 310 and the second connecting member 112 in sequence. It should be noted that the present application does not specifically limit whether a limit portion is provided at both ends of the body length of the connecting rod 330, as long as the two ends of the body length of the connecting rod 330 can pass through the side walls of the first and second connecting members (111 and 112). The connecting rod 330 passes through the body width direction of the threaded rod 310, so the passing direction of the connecting rod 330 for insertion and connection and withdrawal and disassembly is the body width direction of the threaded rod 310. As the sealing nut 320 rotates, the cover 200 and the connecting part are relatively displaced along the length direction of the threaded rod 310 and gradually become close to each other, and the connecting rod 330 also presses against the inner wall of the connecting hole, the pressure increases, and the friction becomes larger. Therefore, regardless of whether limiting parts are set at both ends of the length of the connecting rod 330 passing through the first and second connecting parts (111 and 112), the connecting rod 330 is difficult to fall off the threaded rod 310 and the connecting part. The detachable connection between the connecting rod 330 and the threaded rod 310 is easy to disassemble and the connection is tight.

[0026] In a possible implementation, a first limiting portion 331 is provided at one end of the body length of the connecting rod 330, and the other end of the connecting rod 330 passes through the first connecting member 111, the threaded rod 310 and the second connecting member 112 in sequence. When it is necessary to remove the cover 200 from the tank body 100, first hold the arc handle 321 to rotate the sealing nut 320 so that the sealing nut 320 is away from the connecting portion, the threaded rod 310 no longer exerts a large upward pulling force on the connecting rod 330, the friction force is reduced, and the gap between the lower side of the connecting rod 330 and the upper inner wall of the connecting hole of the threaded rod 310 is enlarged until the connecting rod 330 can be naturally pulled out. At this time, stop rotating the sealing nut 320, hold the first limiting portion 331 to pull out the connecting rod 330, the connection relationship between the threaded rod 310 and the connecting portion is released, the connection relationship between the cover 200 and the side wall of the tank body 100 is released, and the upper cover can be removed. The connecting rod 330 is in the shape of an elongated column, and the first limiting portion 331 is also in the shape of a column. The two are axially consistent and connected. The radial dimension of the first limiting portion 331 is larger than that of the connecting rod 330 and also larger than the diameter of the hole of the connecting rod 330 on the first connecting member 111.

[0027] Further, the end of the connecting rod 330 passing through the second connecting member 112 is provided with a second limiting portion 333, and the second limiting portion 333 is detachably connected to the connecting rod 330. Further, the second limiting portion 333 is T-shaped, and the middle end of the second limiting portion 333 passes through the end of the connecting rod 330 passing through the second connecting member 112, and this end of the second limiting portion 333 (the lower end of the T-shaped, that is, the aforementioned middle end of the T-shaped) passes through the two ends of the connecting rod 330 along the body width direction. That is, the end of the connecting rod 330 passing through the second connecting member 112 is provided with a second limiting hole 332, and the second limiting hole 332 passes through the two ends of the connecting rod 330 along the body width direction, and the middle end of the second limiting portion 333 passes through the connecting rod 330 through the second limiting hole 332, and a preset gap is provided between the second limiting portion 333 and the inner wall of the second limiting hole 332, so that the second limiting portion 333 can be flexibly inserted into the connection and removed and disassembled. The operation of sealing the storage tank is as follows: the cover 200 covers the open end of the tank body 100, and one end of the threaded rod 310 passes through the sealing nut 320 and the outer edge of the cover 200 in sequence and then passes between the first connecting member 111 and the second connecting member 112. The end of the connecting rod 330 away from the first limiting portion 331 passes through the first connecting member 111, the threaded rod 310 and the second connecting member 112 in sequence, and the connecting rod 330 is rotated so that the two ends of the second limiting hole 332 are respectively facing upward (in the direction shown in the figure) and downward (in the direction shown in the figure, toward the ground), and the second limiting portion 333 passes through the second limiting hole 332 from the top of the connecting rod 330, and the opposite ends of its T-shaped structure serve as its limiting portions to prevent the second limiting portion 333 from falling from top to bottom.

[0028] In a possible implementation, there are more than two sealing parts, each of which includes a threaded rod 310, and the number of threaded rods 310, sealing nuts 320 and arc handles 321 is consistent and connected one by one.

Further, there are preferably three sealing parts.

[0029] In a possible implementation, a sealing ring 120 is provided between the cover 200 and the side wall of the open end of the tank body 100. The sealing ring 120 is coaxially arranged with the tank body 100 to buffer the pressure applied by the sealing part on both sides of the cover 200 and the tank body 100, and improve the sealing performance by using its own elastic deformation. Furthermore, an annular groove is provided on one side of the cover 200, and the annular groove matches the open end of the tank body 100, and the open end of the tank body 100 is inserted into the annular groove. The sealing ring 120 is located on the side wall of the open end of the tank body 100, and is sleeved in the annular groove. Its two axial ends are respectively abutted against the inner wall of the end of the annular groove away from its opening and the side wall of the open end of the tank body 100.

[0030] In a possible implementation, a pressure gauge 400 is further included; the pressure gauge 400 is located outside the sealed storage tank, the pressure gauge 400 is connected to the side of the cover 200 facing away from the tank body 100, the detection end of the pressure gauge 400 passes through the cover 200 and enters the preset cavity, the pressure gauge 400 is suitable for detecting the internal pressure of the tank body 100, detecting and displaying the pressure value in real time, and performing explosion-proof intervention (for example, loosening the sealing nut 320 or using the pressure relief safety valve 600 to relieve pressure), so as to ensure the storage safety performance of such sealing elements. Furthermore, it also includes a three-way pipe 500, one end of which is opened and connected to the detection end of the pressure gauge 400, that is, the detection end of the pressure gauge 400 passes through the cover 200 through the three-way pipe 500 and penetrates into the preset cavity; the other end is opened as the air inlet and outlet 510 of the sealed storage tank, and the air inlet and outlet 510 of the sealed storage tank is provided with an opening and closing valve. The air inlet and outlet 510 of the sealed storage tank is suitable for connecting with a vacuum device or an air source device to evacuate the preset cavity of the sealed storage tank / flushed with protective gas; the remaining end passes through the cover 200 and enters the preset cavity of the tank body 100.

[0031] In a possible implementation, a pressure relief safety valve 600 is further included; the cover 200 is provided with a first opening, the first opening of the cover 200 is provided with the pressure relief safety valve 600, one end of the pressure relief safety valve 600 is communicated with the preset cavity of the tank body 100, and the other end of the pressure relief safety valve 600 faces the outside of the sealed tank. The pressure relief safety valve 600 is sealed and connected to the first opening of the cover 200 through a fixing nut.

[0032] In a possible implementation, a buffer gasket 322 is provided between the sealing nut 320 and the sealing cover 200 , and the buffer gasket 322 is annularly sleeved on the threaded rod 310 .

[0033] In a possible implementation, the outer edge of the cover 200 protruding from the radial side wall of the tank body 100 is provided with a groove-shaped notch 210, and the threaded rod 310 is suitable for passing through the two ends of the cover 200 through the groove-shaped notch 210, and the outer walls of the two radial ends of the sealing nut 320 protrude from the opposite side walls of the groove-shaped notch 210. The groove-shaped opening of the groove-shaped notch 210 matches the threaded rod 310, and the groove-shaped opening of the groove-shaped notch 210 faces the body width side of the threaded rod 310. The threaded rod 310 is suitable for being detachably connected to the cover 200 through the groove-shaped notch 210.

[0034] When the storage tank needs to be sealed, the threaded rod 310 is suitable for passing through the groove-shaped notch 210 of the cover 200 from the groove-shaped opening.
